Abstract

The invention relates to the technical field of industrial control, and specifically relates to a novel real-time interactive PLC device. The PLC device comprises a bus, a microprocessor, an input unit, an output unit, a storage unit, a communication interface, an expansion interface, and a power module. The PLC device is characterized in that the input unit, the output unit, the storage unit, thecommunication interface and the expansion interface are connected with the microprocessor through the bus; the microprocessor comprises a calculator and a controller; the input unit comprises an input port and an input processing module; the output unit comprises an output port and an output processing module; the microprocessor operates CANopen, Profibus, EtherCAT, Modbus, Ethernet/IP, DeviceNetand a serial communication protocol. The substantial effects of the invention are that a PLC is provided with a key board and a display screen device, thereby achieving the real-time interaction function of the PLC device; an operation configuration unit is used for enabling the PLC to conveniently cooperate with devices with different protocol standards.

Description

technical field [0001] The invention relates to the technical field of industrial control, in particular to a novel real-time interactive PLC device. Background technique [0002] PLC stands for Programmable Logic Controller, which is a digital computing operation electronic system specially designed for application in industrial environments. It uses a programmable memory to store instructions for performing logic operations, sequence control, timing, counting, and arithmetic operations, and controls various types of mechanical equipment or production through digital or analog input and output. process. When the PLC is put into operation, its working process is generally divided into three stages, namely input sampling, user program execution and output refresh. The completion of the above three stages is called a scan cycle. During the entire operation, the CPU of the programmable logic controller repeatedly executes the above three stages at a certain scanning speed. ...
